GAS-.BORUIBBEB.

To all whom it may concern:

Be it known that I, AL mn'r L. GALUSIIA, of Dorchester, in the county ofSuiiolk and State of Massachusetts, have invented certain new and usefulImprovements in Gas- Scrubbers; and I do hereby declare the following tobe a full, clear, and exact descri tion of the invention, such as willenab e others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in gas apparatus, and more.particularl to washin and scrubbing means,one 0 ject of the inventionbeing to construct a scrubber in such manner that a maximum number ofcontacting surfaces for gas ladened with moisture and extraneous matter,will be afiorded, and so that a maximumnumber of sharp angles will behad,,at the same time confining the parts to a comparatively small spaceand reducing the number of baflie lates employed to a minimum.

A fi irther object is to so construct a gas scrubber that the aspassages will be automatically increased or diminished in size so that,regardless of the as assing, its velocity Wlll be maintains su cientlyhigh to.

throw off, against thesurfaces, water, tar and impurities which the gasmay contain.

With these objects in view the invention consists in certain-novelfeatures in construction and combinations of arts as hereinafter setforth and pointe out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof an apparatus embodying my improvements. Fig. 2 is a plan view artlyin section. Fig. 3 is a horizontal sectional view of a-portion of thescrubber. Fi s. 4 and 5 are views of the baille lates. ig. 6 is a faceview of one of the thin bafile plates, and Figs. 7 and 8 are viewsillustrating a modification.

1 represents a vertical shell, preferably made with a curved wall 2 toaccommodate the cylindrical wall of a vaporizer (not shown) or othercylindrical part of a gas alpparatus from which gas enters said shell trough an inlet 0 ning 3 near the up er end thereof. The s ell 1 containsa chamber 4' which terminates at its lower and above the bottom of saidshell and is chamber a body of insolub e material 6, such,

for instance, as gravel. A water jet 7 dis-' Specification 0! LettersPatent.

4 and the water and gas in their circuitous passage through the mass 6.become intimately commingled. The water, as such, containing some of theimpuritiesof the gas, will settle in the bottom of this shell and thenflow off through a pipe 8, the u per end of which projects a short,distance a ove the bottom' of said shell.

The gas, laden with moisture and containing extraneous elements, willpass from the lower end of the chamber 4 u wardly through a duct 9 andenter the scru ber 10. This scrubber comprises a casing 11 dis.- posedin an inclin osition, as clearly shown in Fi 1. Within the casing 11 twoseries of ha e plates 1213 are located. The baffle plates 12 are madeintegral with and project upwardly from a plate 14 which rests u on theinclined bottom of the casing 11 so t at said baflle plates themselveswill be disposed in inclined positions. Each baifle plate 12 is providedabove the lower end thereof with a series'of. perforations 15 for thepassage ,of water (charged with impurities) which. will become depositedin the bottom of the chamber 11, as will be hereinafter more fullyexplained. Each baflle plate 12 is also provided with a series of elonated slots on openings 16 and beprojections 17 which serve to extend thesurface area of the plate and also aiford a number of sharp angles whichthe moisture laden gas must turn and thus cause the same to be thrownagainst the adjacent surfaces,

.upon which the moisture and the impurities contained therein willbecome deposited. The baflie plates 13 alternate with the baffle plates12 and are made integral with a as tween t ese slots or openings withribs or supporting plate 18 from which they depend. Each bafile plate 13is provided with a series ofangular ribs or rejections 19 similar inform and having t e same functions as the ribs or projections 17 of. thebaffle plates 12; Between the ribs or projections 19, the battle plate13 is provided with a series of slots or assages 20. A series of thin,transverselyisposed plates 21 assbaffle plate 12 and will impingeagainst the V-shaped walls formed by the inner faces of the IlbS orprojections 19 on the adjacent baffie plate 13. Some of the moisture andforeign matter will become deposited upon these walls of the plate 13and,- running down said walls, will become deposited in the bottom ofthe casing 11. The gas still containing more or less moisture, will flowbetween the plates 12 and 13 and in its passage through the openings 20in plate 13, more moisture and impurities will become deposited upon thethin transverse plates 21 and find their way to the bottom of the casing11 in the same manner as before explained. After passing through theopenings 20 the moisture laden gas (now relieved of a ortion of theextraneous elements which it contained) will impinge against additionalsurfaces afforded by projections of plate 13 and of the next plate 12and also by the walls of said lates and more moisture with theimpurities which it carries will become deposited on these surfaces and,

running down the same will become deposited in the bottom of casing 11.The gas.

- the water and impurities accumulate in the bottom of the casing, thesame will overflow through the'perforations 15, thus passingsuccessively from the chambers 26 formed by the lower ortions of theplates 12 and finally from t e last ofthese chambers 26 along the bottominclined wall of the easing 11 and through the passage 9 into thebottom" of the shell 1 and be discharged through the waste pipe 8.

The gas in passing between the baflle plates 1213 must have sufiicientvelocity at all times so as to throw the extraneous elements removed atthe plates 21 near enough to the surface thereof to permit capillaryattraction to draw them from the gas and keep them in contact with thesurfaces afforded by the baflle plates. This of course means certaindifferences in as pressure between the baflle plates 12 and 13. Withvariable volume of gas passing and the constant velocity desired, thearea of the as passages must vary. To accom lish this the baflle plates13 are so mounte that they can move relatively to the baffle plates 12.For this purpose the supporting late 18 of the bafe plates 13 is provieg with lugs 27 for the attachment of the lower ends of links positionsof the baffle plates 13 is maintained under normal conditions, by meansof a spring 31 which bears against one of the links 28. A stop 32 may beformed in one of the other enlargements 29 to engage the link thereinand limit the movement of the baffle plates 13 in the direction of theflow of gas through the scrubber. With this construction, gravity andthe manually adjust able pressure of the spring 31 will tend to keep thebaffle plates 12 and 13 together. The difference in gas pressure a 24and at 25 will tend to move said plates apart and when gas is flowing,balances the opposed pressure which is constant. Consequently thedifference in gas pressure is constant and this constant difference ingas pressure gives constant velocity of gas, which is desired.

In the construction of battle plates shown in Figs. 7 and 8, each plate33 is made with a series of gas passages 34, the parallel walls of eachof which are formed partially by means of parallel flanges 35 whichproject laterally from both faces of each plate and the flanges on oneplate are so disposed relatively to the flanges and gas passages of theadjacent late t at they wil alternate therewith. T us the moisture ladengas passing through the gas passages of one plate will impinge againstthe body of the adjacent plate and will be caused to make several sharpturns before passing through the gas passages of such adjacent plate.The gas will therefore turn more than 180 between each two deflectionpieces or plates and in fact in both constructions and arrangements ofbaffle plates which I have herein described, a maximum number of sharpangles will be afforded as well as a maximum number and extent ofcontacting surfaces.

It will be observed that the construction and arrangement of partsherein shown and described affords a gas scrubber of reat compactness,made up of simple dup icate parts,-any of which can be easily inspected,cleaned, removed or replaced without disturbing the others. It will alsobe observed that the scrubbing and drying of wet gas are accomplishedsimultaneously in the same zip-- A o paratus and by use of the samedevices.

water (as such) is put into the scrubber and the gas is kept a art fromwater and its movements throu the scrubber. Furthermore by means 0 my imrovements the area of the gas passages wil be automatically .Varied bythe action ofthe gas itself when the volume of gas changes, thus keepingthe velocity of gas through passages in the scrubber approximatelyconstant. or variable oniy within certain limits regardless of .changesin volume of gas passing.
